Answer 1

this snipplet can it be recursive, the basic concept is:

List celdas = new List();
string urlSection=String.empty;    
var estatus = new Phrase();
estatus.Leading = 25;
if (streams != null && streams.Any())
    primero = streams.FirstOrDefault(x => x.Id == enlace.Id);
if (primero != null)
    urlSection = primero.UrlSection;

//For the code and generate hyperlink:
Chunk espacioTab = new Chunk(" " + enlace.Name, baseFontBig );

espacioTab = Visor.Servicios.GeneracionPDF.PDFUtils.GenerarVinculo(" " + enlace.Name, urlSection, baseFontBig);
estatus.Add(espacioTab);
if (incluirPaginado)
{

   if (primero != null)
       actualPage = primero.TotalPages;
   else
       actualPage = 0;

///This is important, generate dots like "...." to chunk end 
    estatus.Add(new Chunk(new iTextSharp.text.pdf.draw.DottedLineSeparator()));

    var linkPagina = new Chunk(actualPage.ToString());
    linkPagina = Visor.Servicios.GeneracionPDF.PDFUtils.GenerarVinculo(actualPage.ToString(), urlSection, baseFontBig );
    estatus.Add(linkPagina);
    resultado.paginaFinal = actualPage;
}

//This is for add to your cell or table
PdfPCell rightCell = new PdfPCell()
{
    Border = PdfPCell.NO_BORDER,
    Colspan = 3,
    PaddingLeft = espacioInicial.Length,
    ExtraParagraphSpace = 10,
};
rightCell.AddElement(estatus);
celdas.Add(rightCell);

And create a new method, this create a hyperlinkand you can invoque when you want

/*Generar Vinculo (create hyperlink)**/
public static Chunk GenerarVinculo(String tituloMostrar, string urlDirecion, iTextSharp.text.Font fuente)
{
    Chunk espacioTab = new Chunk();
    try
    {
        if (String.IsNullOrEmpty(urlDirecion))
        urlDirecion = "Indice de Contenido";

        espacioTab = new Chunk(tituloMostrar, fuente);
        var accion = PdfAction.GotoLocalPage(urlDirecion, false);
        espacioTab.SetAction(accion);
    }                
    catch (Exception error) { }
    return espacioTab;
}
